How to remove MySql apt repo

Question

I was trying to install MySql on my system running Ubuntu 14.04. So I added a MySql apt from the link Steps to fresh install MySql.
After running into a lot of trouble and realizing apt uses libs not supported by Ubuntu 14.04, I was advised to remove the apt and use Ubuntu repo to install mysql.

However, it seems I can't find how to remove the above mentioned apt repo. I've been through some of the stuff I can find on the community but still no solution that worked for me! Software center shows this.

Tried using dpkg, aptitude -remove also from software center but looks like I've hit a wall.
So any help is appreciated.

Answer 1

So I added a MySql apt from the link Steps to fresh install MySql

When those are really the steps that you followed, then this is your solution.

Open a terminal and run this command if you want to remove all configurations:

sudo apt-get purge mysql-apt-config

Otherwise, this command is sufficient:

sudo apt-get remove mysql-apt-config

Answer 2

I found that /etc/apt/sources.list.d/mysql.list had all the references to mysql repositories:

pi@raspberrypi:~ $ find /etc/apt/ -type f | xargs grep "repo.mysql.com"
/etc/apt/sources.list.d/mysql.list:deb http://repo.mysql.com/apt/debian/ stretch mysql-apt-config
/etc/apt/sources.list.d/mysql.list:deb http://repo.mysql.com/apt/debian/ stretch mysql-5.7
/etc/apt/sources.list.d/mysql.list:deb http://repo.mysql.com/apt/debian/ stretch mysql-tools
/etc/apt/sources.list.d/mysql.list:#deb http://repo.mysql.com/apt/debian/ stretch mysql-tools-preview
/etc/apt/sources.list.d/mysql.list:deb-src http://repo.mysql.com/apt/debian/ stretch mysql-5.7

So I decided to remove the mysql.list i the /etc/apt/sources.list.d directory and finaly sudo apt-get update does not come with mysql repositories

Thanks every one here
